MONITORAGGIO DEGLI SPOSTAMENTI E DEL COMPORTAMENTO DEL GRANCHIO BLU CALLINECTES SAPIDUS: APPROCCIO METODOLOGICO E SPERIMENTALE

Abstract

The blue crab Callinectes sapidus is an invasive alien species of Atlantic origin occurring in brackish waters along most Mediterranean shores. The present paper reports about the methods and approach used to investigate the short-scale movements, temperature-related activity patterns and behavior of blue crabs in the S’Ena Arrubia (Sardinia, central Mediterranean Sea) Lagoon. Movements and activity patterns were investigated using acoustic telemetry, while the behavior was investigated using triaxial accelerometers in mesocosm. The investigation is ongoing and the results will be available in the next few months.
